Unistrut®, Wayne, Mich., offers Roofwalks® rooftop walkway systems that are an economical solution to damage caused by rooftop foot traffic. On membrane, built-up, foam and coated roofs, the product protects against puncture, abrasion and wear. On standing-seam metal roofs, workers of all sizes can walk safely on the anti-skid surface without causing seam distortion, “dishing” or harmful stress to roof panels.
